Attaching Speaker to Base
NOTE: For ease of installation, the base can be
attached to the speaker before or after the base
is mounted.

These horns should be mounted 15 to 20 feet
above the floor to allow for best sound
distribution. The units can be mounted to a wall,
a beam or an electrical box.
Mount the base to a wall using the two holes
provided. Knockout holes are provided for
punch out should additional holes be desired.
A "C" clamp is provided with the horns to
allow mounting to a beam. Place the bolt
through the hole in the bottom of the base to
secure the "C" clamp to the beam (See
Figure 1). It is suggested that the horn be
mounted to the underside of the "I" beam to
provide maximum positioning adjustments.
Connection to an electrical backbox is
accomplished by channeling wire through the
ball of the base and making appropriate
connections. The base has holes punched
for a double-gang square box, but by
punching out additional knockout holes, the
base can be mounted to a single-gang or
octagon box (See Figure 2).
The horns may be rotated or moved up and down
to obtain the desired position by loosening the
position adjustment knob (See Figures 1 and 2)
at the bottom of the unit approximately one turn.
Make required adjustments, retighten knob.
